1150 PM EST THU DEC 18 2008

.AVIATION...

THE IMPENDING SNOW STORM WILL HAVE MAJOR IMPACTS ON AVIATION THIS
MORNING AND AFTERNOON. THE LOW PRESSURE SYSTEM OVER KANSAS WILL
RAPIDLY MOVE ACROSS THE NORTHERN OHIO VALLEY TODAY. DEEP LAYER
MOISTURE AND FORCING WILL OVERSPREAD SOUTHEAST MICHIGAN OVER THE
NEXT 3 TO 6 HOURS. THE LATEST MODEL SOUNDINGS INDICATE CONDITIONS
RAPIDLY DETERIORATING BETWEEN 09Z AND 12Z AS SNOW OVERSPREADS THE
AREA. DURING THIS TIME...CONDITIONS SHOULD RAPIDLY FALL FROM MVFR TO
VLIFR. HEAVY SNOW WILL IMPACT THE TERMINALS FOR SEVERAL HOURS AFTER
12Z...WITH RAPID ACCUMULATIONS EXPECTED. IMPROVEMENTS IN CIGS AND
VSBY SHOULD COME TO THE DETROIT TERMINALS AFTER 17Z AS MID LEVEL DRY
AIR WORKS INTO THE AREA FROM THE SOUTH...WITH IMPROVING CONDITIONS
EXPECTED AFTER 19Z AT FNT AND MBS. IN ADDITION TO THE SNOW...
EASTERLY WINDS WILL INCREASE TO 12 KNOTS OR GREATER DURING THE
MORNING AND CONTINUE INTO THE AFTERNOON AS THE LOW PASSES BY TO
THE SOUTH.

.PREV DISCUSSION...ISSUED 1037 PM EST THU DEC 18 2008

UPDATE...

AT THIS POINT...DO NOT PLAN TO MAKE ANY CHANGES TO THE ONGOING
FORECAST WITH RESPECT TO THE APPROACHING WINTER STORM.

THE WATER VAPOR SHOWS AN IMPRESSIVE MID LEVEL WAVE LIFTING UP FROM
THE SOUTHERN PLAINS. CLOUD TOPS HAVE BEEN RAPIDLY COOLING ACROSS
THE CENTRAL PLAINS/WESTERN OHIO VALLEY...WITH RADAR SHOWING
PRECIPITATION STEADILY LIFTING NORTHEAST ACROSS ILLINOIS. THE 00Z
UPPER AIR PLOTS SHOW SOME THINGS OF CONCERN. FIRST OFF IS THE VERY
HIGH MOISTURE CONTENT IN PLACE FROM THE MID MISSISSIPPI VALLEY
THROUGH THE TENNESSEE VALLEY. SECOND IS THE DEGREE OF ELEVATED
INSTABILITY SHOWN ON UPSTREAM SOUNDINGS. THESE FACTORS ALONG WITH
THE STRONG DYNAMIC FORCING EXPECTED TO OVERSPREAD THE REGION LATE
TONIGHT CERTAINLY SUPPORTS THE ONGOING WINTER STORM WARNINGS. THE
00Z NAM MODEL SOUNDINGS AND 00Z DTX SOUNDINGS CONTINUE TO INDICATE
THE BULK OF PRECIPITATION FALLING AS SNOW ACROSS SOUTHERN
MICHIGAN...WITH SOME SLEET STILL POSSIBLE NEAR THE OHIO BORDER.
THE 00Z NAM HAS COME IN A LITTLE STRONGER WITH THE LIFT AND THUS A
LITTLE HIGHER ON TOTAL QPF...CARRYING A LITTLE OVER AN INCH FOR
LOCALS SOUTH OF I 69. AT THIS POINT...TEND TO THINK SNOW ACCUMS
ACROSS THE SOUTH WILL BE ON THE HIGH END OF THE 6 TO 10 INCH
RANGE.

THE FORCING CONTINUES TO LOOK THE STRONGEST BETWEEN 09Z AND 15Z
AND CONTINUES TO INDICATE SNOWFALL RATES OF A GOOD 2 OR MORE
INCHES PER HOUR FRI MORNING.

PREV DISCUSSION...ISSUED 704 PM EST THU DEC 18 2008

UPDATE...

WILL ISSUE AN EVENING UPDATE TO THE FORECAST SIMPLY TO ADJUST FOR
THE LATEST TRENDS IN THE TEMPERATURES. MAINLY CLEAR SKIES THIS
EVENING ALONG WITH FRESH SNOW COVER AND LIGHT WINDS HAVE ALLOWED
TEMPERATURES TO RAPIDLY DROP SINCE SUNSET. MOST LOCALS HAVE
ALREADY HIT OR FALLEN BELOW THE FORECAST MIN TEMP. SO WILL UPDATE
TO LOWER TEMPS TONIGHT. CLOUDS WILL BE ON THE INCREASE OVERNIGHT
IN ADVANCE OF THE APPROACHING STORM SYSTEM...SO TEMPERATURES
SHOULD BEGIN TO RISE LATER IN THE NIGHT.

PREV DISCUSSION...ISSUED 335 PM EST THU DEC 18 2008

SHORT TERM...TONIGHT/TOMORROW

SHORT DURATION/HIGH IMPACT SNOWSTORM TO HIT DURING THE MORNING RUSH
HOUR. NO CHANGES OR UPDATE WILL BE MADE TO THE 1232 PM WSW.

WATER VAPOR IMAGERY SHOWS A SHORTWAVE TROUGH TRACKING THROUGH
ONTARIO AT THE PRESENT TIME...WITH NORTHWEST UPPER LEVEL CONFLUENT
FLOW AND SURFACE HIGH PRESSURE TO FOLLOW FOR TONIGHT/TOMORROW. THE
STRONG SURFACE HIGH OVER CENTRAL CANADA WILL BE IMPORTANT AS THE
STRONG UPPER WAVE NOW OVER THE FOUR CORNERS REGION RACES OFF TO THE
NORTHEAST...EVENTUALLY HOOKING EASTWARD. A LOOK AT THE 12Z HIRES
EUROPEAN CONTINUES TO GENERALLY SUPPORT THE PREVIOUS FORECAST...AS
THE 700 MB LOW TRACK LOOKS TO BE THROUGH/ALONG THE I-69
CORRIDOR...WITH FAIRLY WELL DISTRIBUTED QPF OF 0.5 INCHES TO 0.75
INCHES ACROSS THE CWA...AS THE LOW LOOKS TO PEAK OUT IN INTENSITY
FRIDAY MORNING OVER THE WESTERN OHIO VALLEY. A QUICK LOOK AT THE 18Z
NAM SHOWS THE SURFACE LOW CONTINUING TO DEEPEN DURING THE DAY...AS
THE 500 MB LOW IS DEEPER OVER EASTERN IOWA (541 VS 544 DAM) AT 12Z
FRIDAY. AS SUCH...THE 18Z NAM IS MORE ROBUST WITH THE QPF AND A
BIT FARTHER NORTH. THINKING THE NAM IS A BIT OVERDEVELOPED...AND
DUE TO THE SPEED OF THE SYSTEM/DURATION...WOULD BE SURPRISED IF WE
EXCEEDED OUR FORECASTED SNOWFALL TOTALS OF 6 TO 10 INCHES. LESS
SNOWFALL IS STILL EXPECTED TOWARD THE OHIO BORDER WITH A PERIOD OF
SLEET LIKELY MIXING IN...AS WELL AS DUE TO THE MID LEVEL DRY SLOT
MOVING IN...WHICH WILL TAPER OFF PRECIPITATION QUICKLY.

WITH THE LOW STRATUS BREAKING UP THIS AFTERNOON AND CALM
WINDS...THERE IS A PRETTY GOOD CHANCE OF TEMPERATURES DROPPING INTO
THE TEENS (ESPECIALLY THUMB REGION) BEFORE CLOUDS RETURN OVERNIGHT.
HAVE UNDERCUT GUIDANCE BY A COUPLE DEGREES.

LONG TERM...FRIDAY NIGHT THROUGH THURSDAY

AND NOW FOR THE REST OF THE STORY.

THE PATTERN REMAINS VERY ACTIVE IN THE EXTENDED PORTION OF THE
FORECAST AS SEVERAL MORE SIGNIFICANT STORM SYSTEMS REMAIN ON THE
HORIZON.

THE FIRST OF THESE WILL SWING INTO THE CENTRAL GREAT LAKES OVER THE
WEEKEND. PER WATER VAPOR IMAGERY/UPPER AIR DATA...THE MAIN CORE OF
THIS STORM SYSTEM IS DROPPING SOUTHEAST FROM VANCOUVER ISLAND INTO
WASHINGTON STATE. THIS UPPER LOW WILL CROSS THE NORTHERN ROCKIES
LATE FRIDAY NIGHT INTO SATURDAY AND THEN DEEPEN RAPIDLY AS A STRONG
JET STREAM/DISTURBANCE RACES INTO THE BASE OF THE SYSTEM AND PHASES
WITH AN EXPANSIVE SOUTHERN STREAM JET STREAM. THE RESULTANT JET CORE
OF 150+ KNOTS WILL THEN NOSE UP INTO THE CENTRAL/EASTERN LAKES AREA
AND RESULT IN RAPID CYCLOGENESIS.

MODELS ALL AGREE THAT A MAJOR STORM SYSTEM WILL DEVELOP OVER/NEAR
THE AREA IN SUCH A SCENARIO...BUT VARY ON THE TIMING AND LOCATION OF
THE PHASING OF THE TWO STREAMS. THIS WILL ULTIMATELY DETERMINE THE
LOCATION OF HEAVIEST SNOWFALL IN THE SATURDAY NIGHT TO SUNDAY TIME
FRAME. THAT SAID...CONFIDENCE IS RELATIVELY HIGH THAT SEVERAL INCHES
OF SNOW WILL FALL OVER THE AREA AS THIS WINTER STORM FORMS OVER THE
AREA. THE CHALLENGE OVER THE SEVERAL DAYS WILL BE TO DETERMINE IF
THIS WILL EVOLVE INTO ANOTHER SIGNIFICANT SNOW STORM FOR ALL/PARTS
OF THE AREA. IT CERTAINLY HAS THIS POTENTIAL AS IT WILL BE A MORE
DYNAMIC SYSTEM THAN THE LATE WEEK SYSTEM. IF NOTHING ELSE...EXPECT
STRONGER SURFACE LOW PRESSURE TO BRING MORE WIND WITH THIS STORM.

YET ANOTHER SIGNIFICANT STORM SYSTEM WILL THEN TRACK INTO THE CONUS
ON THE HEELS OF THIS ONE. THIS SYSTEM IS JUST NOW DROPPING THROUGH
THE ALEUTIAN CHAIN AS OF TODAY...SO DETAILS WILL HAVE TO WAIT UNTIL
THESE CURRENT TWO SYSTEMS ARE OUT OF THE WAY.

TEMPERATURES WILL REMAIN COLD THROUGHOUT THE FORECAST PERIOD...WITH
HIGHS GENERALLY IN THE UPPER TEENS TO 20S AND LOWS IN THE UPPER
SINGLE DIGITS TO TEENS.

MARINE...

EASTERLY WINDS WILL BE ON THE INCREASE LATE TONIGHT AND ESPECIALLY
TOMORROW AS A STRONG LOW PRESSURE SYSTEM SLIDES THROUGH THE NORTHERN
OHIO VALLEY. GALE FORCE WIND GUSTS ARE EXPECTED ACROSS THE OPEN
WATERS OF LAKE HURON...WITH GUSTS ALSO APPROACHING GALE FORCE ALONG
THE NEARSHORE WATERS. WINDS WILL SLOWLY DECREASE FRIDAY NIGHT.
HOWEVER...WAVES MAY REMAIN HIGH THROUGH THE NIGHT OVER AREAS THAT
ARE STILL ICE FREE GIVEN THE PREVAILING ONSHORE FLOW ACROSS LAKE
HURON.  WINDS WILL REMAIN OUT OF THE EAST AND STRENGTHENING AGAIN
OVER THE WEEKEND AS ANOTHER LOW PRESSURE SYSTEM TRACKS THROUGH THE
GREAT LAKES.
